A new project called QuickBEAM enables running Rails applications on the BEAM (Erlang VM) using JavaScript, providing Erlang's famous fault tolerance and concurrency model to web applications. When a JavaScript runtime crashes, only that specific process is restarted while others continue serving requests, maintaining WebSocket connections and application state. This approach brings telecom-grade reliability to web applications without changing the Ruby source code.
Background
The BEAM is the virtual machine that runs Erlang and Elixir, known for its exceptional concurrency and fault tolerance capabilities originally developed for telecom systems. Rails is a popular Ruby web framework that traditionally runs on Ruby interpreters.
